A black hole is an extremely weird( )object. Its intense gravitational field changes space and time in fundamental ways. Each black hole has only three measurable properties () : mass (), electrical charge () and rotational momentum ().

It spins () in the center of a rotating whirlpool () of hot gas and dust, slowly sucking ( ) it in.
